A device which identifies different types of charged particle when they pass through and ionize a super saturated vapor.Our cloud chamber Ionization [1]Cosmic ray entering Earth by WikiThe magnetic field can be used to determine the charge of a particle!Cosmic Ray Trails Straight track 'kinking' off left/right sharply : Muon decay. Zig zag track : Low energy cosmic ray bouncing from atoms (multiple scattering). Skinny straight tracks : High energy Muon particles barreling through Detector. Three tracks meeting at a point : One is cosmic ray, other is outoging electron hit by cosmic ray, last is the outgoing cosmic ray itself.

IonizationObjectives of the PROJECTParticles by WikiTHANK YOU FEEL FREE TO ASK QUERIES :-)As per our experiment Count rate of cosmic rays increases at night as compared to day which is in total agreement to expected results.According to Blackett, pressure level in the atmosphere, where most of the muons are formed, increases as the atmospheric temperature increases .consequently more muons decay before reaching the groundTo build a detector that is easy to build, cheap and has some kind of usable output to graph, visualize etcTo study influence of magnetic field on cosmic rays, their count rate dependence and their density in our cloud chamber.on time of day,orientation1) Effect of magnetic field on cosmic ray.2) Count rate v/s orientation of the cloud chamber.3) Count rate v/s time of day (day & night4) Count rate per unit volume per unit time

As per the our experiments the count rate of cosmic rays are MORE in N-S direction than in the E-W direction.It is in agreement to earlier experiments carried out by various research institutes.As per a research in Tasmania the ratio was 0.272 in N-S direction and 0.212 in E-W direction.Results Obtained : DAYEvent 1)Time of Observation : 3 min Rays witnessed : 30Event 2)Time of observation : 2 min 30 secRays witnessed : 25Event 3)Time of observation :3 min 10 secRays witnessed : 32
